Capture the flag can be fun, but Karel Bousson has put a new spin on the game that allows you to compete against neighbors over who can keep a single item — a modified tool case — in their possession the longest. The box contains an Arduino Mega that interfaces with an RFID reader to […]
Ivan Miranda has come up with a novel method for drawing messages in the sand, using a tread assembly that prints as it travels along the beach. The robot uses a length of square tubing to connect a pair of half tanks, with 50 SG90 micro servos spaced out on the bottom. As it pulls […]
Today, we’re announcing a new security feature for our community: two-factor authentication (2FA) on Arduino web services. We have implemented a two-step verification login to arduino.cc, so our users can be sure of their online safety. If enabled, two-factor authentication offers an additional security layer to the user’s account, so the user can have better […]
If you’d like to build a walking biped robot, this 3D-printed design by Technovation looks like a fantastic place to start. Each leg features three servos that actuate it at the hip, knee, and ankle for a total of six degrees of freedom. Control is handled by an Arduino Uno board that rides on top […]
Cycling can be fun, not to mention great exercise, but is also dangerous at times. In order to facilitate safety and harmony between road users on his hour-plus bike commute in Marseille, France, Maltek created his own LED backpack signaling setup. The device uses a hand mounted Arduino Nano 33 BLE Sense to record movement via […]
While electronics and water don’t generally mix, researchers at Ochanomizu University in Japan have come up with an ephemeral display method that uses floating clusters of bubbles to show messages on a liquid surface. The device, known as UTAKATA, utilizes a line of seven electrodes under Arduino Uno control that activate to form hydrogen bubbles via […]
If you miss your Tamagotchi virtual pet from the ’90s, Element14 Presents’ DJ has come up with the next best thing — or perhaps something even better! His DIY device, named “Tomo” for friend, displays a digital companion on its 1.3” OLED screen, and features a variety of mini games that lets you level it up […]
Machine learning (ML) algorithms come in all shapes and sizes, each with their own trade-offs. We continue our exploration of TinyML on Arduino with a look at the Arduino KNN library. In addition to powerful deep learning frameworks like TensorFlow for Arduino, there are also classical ML approaches suitable for smaller data sets on embedded […]
Max Danilin created an automatic barrel piano that outputs MIDI signals, not through an SD card or internal memory, but by reading sheet music encoded on paper as black dots and dashes. The sheet is pulled under an array of 40 optocouplers using a hand crank — or even power drill — providing musical info to the […]
Today, we are excited to announce the arrival of the Arduino IDE 1.8.13. Significant improvements include fixing the crash on Mac OS X with multiple monitor setups and resolving the recent package_index.json issue without other user intervention. You will also notice that the boards listed in the “Tools” menu are now grouped by platform, making […]
